Optimizing eDNA to Detect Multiple Aquatic Invasive Species

Little information exists to guide the development of widespread, multi-species environmental DNA monitoring for AIS. This project will answer questions regarding the optimal amount of sampling effort, timing, and sample location for detecting AIS across a range of lake types and AIS abundances. Results will guide widespread monitoring to establish statistically valid estimates of AIS prevalence and for early detection efforts.

Objectives

1) Determine the effects of lake characteristics and seasonality on AIS detection probability using eDNA.

2) Optimize field and lab methods for maximizing the detection probability of multiple AIS.

Current progress

We have finished eDNA sampling 21 lakes throughout Minnesota. Right now, we are processing samples to detect AIS. Although our findings are forthcoming, we are excited to share them with you!

This research is conducted in collaboration with the Natural Resources Research Institute and the University of Illinois and is funded by the Minnesota Aquatic Invasive Species Research Center with funds from the Environment and Natural Resources Trust Fund.
